A New Classification of Technologies

This study here suggests a classification of technologies based on taxonomic characteristics of interaction between technologies in complex systems that is not a studied research field in economics of technical change. The proposed taxonomy here categorizes technologies in four typologies, in a broad analogy with the ecology: 1) technological parasitism is a relationship between two technologies T1 and T2 in a complex system S where one technology T1 benefits from the interaction with T2, whereas T2 has a negative side from interaction with T1; 2) technological commensalism is a relationship between two technologies in S where one technology benefits from the other without affecting it; 3) technological mutualism is a relationship in which each technology benefits from the activity of the other within complex systems; 4) technological symbiosis is a long-term interaction between two (or more) technologies that evolve together in complex systems. This taxonomy systematizes the typologies of interactive technologies within complex systems and predicts their evolutionary pathways that generate stepwise coevolutionary processes of complex systems of technology. This study here begins the process of generalizing, as far as possible, critical typologies of interactive technologies that explain the long-run evolution of technology. The theoretical framework developed here opens the black box of the interaction between technologies that affects, with different types of technologies, the evolutionary pathways of complex systems of technology over time and space. Overall, then, this new theoretical framework may be useful for bringing a new perspective to categorize the gradient of benefit to technologies from interaction with other technologies that can be a ground work for development of more sophisticated concepts to clarify technological and economic change in human society.
